The Justice Department filed an appeal challenging its loss in the AT&T-Time Warner antitrust trial on Thursday, according to a court filing. AT&T completed its $85 billion acquisition of Time Warner a few weeks ago after a federal judge rejected the Justice Department’s argument that the deal would be anti-competitive.
The case has been closely watched as an indicator of how courts would treat mergers of companies in different industries. AT&T is one of the country’s biggest telecom providers and its purchase of Time Warner allowed it to pick up some of the biggest media brands in the U.S., including HBO and CNN.
AT&T didn’t immediately respond to a request for comment.
